Risk factors of visual deterioration by uni- and multivariate analyses.
| Variable | Univariate analysis | Multivariate analysis | ||
|---|---|---|---|---|
| HR (confint) | p val | HR (confint) | p val | |
| Age | 1.79 (0.33-9.72) | 0.5 | ||
| Diagnosis | 1.38 (0.26-7.34) | 0.7 | ||
| Tumor site | 1.14 (0.13-9.76) | 0.91 | ||
| Cyst formation | 14.09 (2.27-87.44) | <0.001 | 46.08 (2.98-713.59) | 0.01 |
| VA at baseline | 0.86 (0.17-4.26) | 0.71 | 0.2 (0.01-2.789) | 0.23 |
| Tumor volume | 1.41 (0.25-7.95) | 0.87 | 24.64 (0.6-1019) | 0.09 |
| Marginal dose (BED) | 3.54 (0.71-17.71) | 0.11 | 239 (3.3-17349) | 0.01 |
BED: biologically effective dose. p val <0.15 suggests statistically significant in univariate analysis. p val <0.05 suggests statistically significant in multivariate analysis.
